        RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("FileLength"))

VB.NET doesn't support anonymous delegates so there is no direct conversion of this. http://social.msdn.microsoft.com/Forums/en-US/csharpgeneral/thread/08c82be8-bf9a-4a03-b366-b2d8c503e1d1[^]

So what is the way to do the same. the senerio is i have a delegate defind say "ProgressChangedEvent" i my class i have a event "UploadProgressChanged" of type "ProgressChangedEvent" now RaiseEvent ProgressChangedEvent(me,args) working fine for me, but i want the asyncronous call, so want to use. dispature.beginInvoke( ) so how could i call the event. Thanks Plz help...

Drop the "Do" - this is a bug in the converter you used. You can drop the 'End Function' since it's just a single statement. Which version of VB are you using? If you're using VB10 (VS 2010), change the 'Function' to 'Sub' since nothing is being returned.

Hi David, Thanks for the reply is am using VS2008 SP1. My Code is like below

Me.Dispatcher.BeginInvoke(Function() Do
RaiseEvent PropertyChanged(Me,New PropertyChangedEventArgs("UploadPercent"))
End Function)

As per your instructions i have change it to

Me.Dispatcher.BeginInvoke(Sub
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("UploadPercent"))
)

But it is again not working for me.... Possible solution??? Thanks

For 2008, you'll need:

Me.Dispatcher.BeginInvoke(Function() AnonymousMethod1())

Private Function AnonymousMethod1() As Object
PropertyChanged(Me, New PropertyChangedEventArgs("FileLength"))
Return Nothing
End Function
